Specification forming part of Letters Patent 0., l7 6,658,dated-April 25, 1876; application filed December 16, 1575.

To all whom it may concern: I Be it. known that I, ALLEN R. MGBROOM,

ot Gibsonville, in the county ot' Hocking and,

State of Ohio, have invented certain newand 'uset'ul Improvements in' Tiling-Machines and i being had to the accompanyingdrawii ig, and to the letters ot'ref'erence marked thereon,v

which form a part of this specification.

My invention relates to' n achines for making pipetiling for pump-stocks, of plastic clay,

or any suitable composite.

My objectis to simplify'the operation and the machine for making the-tile. I v

I employ a sectional flask, in which the sections, when joined, are secured by embracing strap-clamps,-fitting over vertical Wedges at the corners of the flask, there being one of these strap-clamps at the bottom and one at the top, and, fitting down over the Wedges, draw hard upon the flask-sections in the line of their walls, and hold them firmly together. The flask or mold is the counterpartof the tile, and its ends are closed by plates, which have openings to receive a plunger-core. This plunger-core is forced downthrough the plastic material, which is previously packed in the flask,'and, pressing the material into cavities at the ends of the flask, forms the flanged or shouldered ends of the tile and the central opening therein, and discharges the surplus material out at the central opening in the bottom of the flask and at thebase of the frame. In this movement the plunger-core is operated by a vertical rack on its stem, and a pinion carried by an upright frame.

, cross-guide, to allow of the removal and replacement of the flask, while the descent of the plunger-guide is limited by the collar-stop striking the lower cross-guide.

I The particular features which constitute my i n ention will be. specifically pointed out'in the claim.

n the accompanying drawings, Figure 1 represents. a vertical sectional view'ofa tilingmachine embracing my -invention, and show-- ing the plunger at its downstroke through the flask; Fig. 2, a similar view, showing the, plunger at the limitof its upstroke; Fig.3, a horizontal section through the flask; Fig, 4, a

view in perspective of the flask with its corner wedges andthe .einbracin gstrap-clamps and Fig. 5, an interior-view of one section of the I employ aivertical frame, consisting. of a" base, A,,:from which twoiside posts, B B, rise, suitably braced, and connected by cross-guides.

0 0*, one near the top and one near the bottom, and which serve as the guides/for the plunger D and its operating-stem E, the latter I forming a cogged rack, a, and operated by a pinion, E, on a horizontal crank-shaft, supported in the side posts.

-tile. The ends of the sections are provided placed, to clamp and hold the sections together while forming the tile. The greatest projection of these wedges is at the bottom of the flask, and the strapclamps are made to fit over and embrace these wedges at the top and bottom, and seat themselves tightly around the flask and hold its sections secure. They form very simple and convenient braces, and admit of easy adjustment upon and removal from the flask. They can be wedged tightly down upon the inclined corners, and easily slipped'ofl' to open the clasp to remove the finished tile, as they require nofastening when on the flask-Wedges. v

One section of the flask is filled with the material to form the tile. The other section is then fitted upon it, and secured by dowelpins g. after which the embracing strap-clamps are driven on, and the flask placed upon the base A, and centered with the plunger-core by base-cleats h It, which form ways at the sides and a stop, to limit the movement of the flask as it is slid on its end in upon the base to bring its central openings coincident with the opening f in the base and the plunger-core. The plunger-core is pointed, -and is driven down through body of the material in the flask, and, forcing the material into the end recesses 12 in the flask, forms the end head or flan-ges on the tile,'and forces the surplus material out at the bottom of the flask and the base-opening.

In. this action it is' necessary that the plunger should be limitedboth in its descent and ascent, and this is done by a collar, i, on the head of the plunger-core strikingthe lower cross-guide C, so that the plunger end must only enter the base-openingf informing the tile; and when drawn up this collari is arrested by the pinion F, so as to bring the plunger end within its guide opening, and by this means the plunger iscaused to operate within certain limits by turning the crank j to the right or left.

The cogged rack a passes through the upper cross-guide, which, with the lower crossguide, formsupper and lower ways, to steady the plunger-core. Y

Different-sizedplunger-cores may be used -to form the tile-conduit of different diameters by having a guide-plate, s, secured to the under side of the lower cross-guide O and changing this plate 8 tosuit the size of the plunger-core, the opening in the cross-guide (1 being large enough for the largest plungereore that may be used.

By this method of forming the tile it is made without flaws, and from the solid body of the plastic material, and in a very expeditions manner. They are chiefly designed for formin g pump-stocks, by bolting their flanged ends together, with a packing between them.

Tile fitting into each other may be made as well by slight changes in the flask and the plunger. p

. I claim- In a tilemolding machine, the sectional mold, provided with the end plates 0 c and vertical corner wedges 00, and combined with the plunger D, clamps H H, the opening f,-and the base-guides h, the plates having central openings d d, and the plunger a stop, 1', all arranged'to operate as herein set forth.

In testimony that I claim the foregoing I have affixed my signature in presence of two witnesses.

ALLEN R. MoBROOM.
